By the way , the legend about the mythical King Arthur Pendragon also is centred around Celtic history . . .
The truth behind the legend . . . Arthur is said to have been a Celtic ruler who fought against the invasion of the Anglos and the Saxons ( both Germanic tribes . . .). . . Merlin is said to in reality have been a druid who aided Arthur ( his real name is said to have been 'Myrdin' . .) . .
( Concerning history : All of the British Isles ( today's U.K. and Ireland ) were once inhabited by 100 % Celtic/Gaelic peoples . .The invasion of the Germanic tribes of the Anglos and the Saxons founded the state of England ( Eng
land = 'land of the Anglos
' ) while mostly pushing the original peoples towards Scotland in the north and towards Wales in the west . . . )
Just that during medieval times the saga was twisted , making Arthur actually a mythical Anglo-Saxon king . . . . .
Whatever , the saga is popular . . . .
Especially Arthur's mythical knight 'Sir Galahad' until today remains some kind of figurehead of what people imagine under a knight .
